KANSAS CITY, Mo. (AP) — A Kansas City, Missouri, 18-year-old is accused of fatally shooting a suburban father who had been trying to sell a gun on a grocery store’s parking lot.

Jackson County prosecutors on Tuesday charged Fazon Swinton with second-degree murder, second-degree robbery, armed criminal action and leaving the scene of a shooting.

Authorities say Jacob Branter of Lee’s Summit was shot and killed April 3 outside a Price Chopper store. Prosecutors allege that Swinton made arrangements to buy a handgun from Brantner but stole it instead, running off before exchanging gunfire with Brantner.

Swinton later was treated at a hospital for a bullet wound.

Online court records don’t show whether Swinton has an attorney.
